The Challenge

ENMG reports depended on manual extraction from medical PDFs, causing slow turnaround and inconsistent report quality.

The Solution

Built an end-to-end platform that converts exam PDFs to structured JSON, applies white-box QA rules, and generates standardized final PDF reports.

Senior Choice

Python pipeline with multilingual extraction (PT/EN), anomaly flags, reference-based analysis logic, and a desktop .exe app for non-technical users.

Veterinary operations had connectivity gaps and manual workflows, causing data loss risk and frequent rework in field routines.

The Solution

Engineered a mission-critical mobile app with offline-first architecture, custom sync engine (SQLite + Supabase), and automated operational workflows.

Senior Choice

Expo/React Native + SQLite for local durability, Supabase for cloud sync, server-wins conflict resolution, tombstones soft-delete, and WhatsApp-native reporting.

The Challenge

Legacy systems causing operational bottlenecks with 15% daily failure rate in SAP integrations affecting warehouse operations.

The Solution

Architected a resilient middleware layer with circuit breakers, retry mechanisms, and real-time monitoring. Implemented event-driven architecture for async processing.

Senior Choice

Chose Laravel over Node.js for the API layer due to mature ORM (Eloquent) for complex Oracle DB relationships, built-in queue workers for SAP jobs, and team expertise reducing onboarding time by 60%.
